Other details about the restaurant are vague. We know that there are only 36 seats and reservations are required. Passengers are only given directions to the restaurant’s secret location after booking a table. Frequent fliers, however, have deduced that the restaurant is located behind the chef Alain Ducasse-helmed Saison restaurant, in Terminal C.

A meal at CLASSIFIED is, predictably, not cheap. Entrees range from $29 to $45 and, according to the menu, there’s also a 42-ounce tomahawk ribeye steak available for $98.

From leaked photos, it appears that customers order their meals via iPad. Although an unconventional choice for an upscale restaurant, the digital ordering process could prove to be a positive feature for diners who must dash to catch a flight.

United’s frequent fliers can check online to see whether or not they have been granted access to the restaurant. It’s yet unclear what exactly will qualify a passenger for a meal at CLASSIFIED.
